Abstract

Ensemble (20) de brosse de mise à la terre comprenant une brosse (30) de mise à la terre et une plaque de montage (40) de brosse configurée pour retenir axialement et radialement ladite brosse (30), ladite brosse (30) comprenant un support (32) et une pluralité de fibres individuelles conductrices (31) montée dans ledit support (32), la plaque de montage (40) comprenant un corps principal radial (42) délimité axialement par une première face frontale (41a) et par une deuxième face frontale (41b), et une pluralité de languettes (46) de retenue axiale et radiale de ladite brosse (30), lesdites languettes (46) étant circonférentiellement réparties autour du corps principal (42) de la plaque de montage (40) et s’étendant axialement depuis la deuxième face frontale (41b) du corps principal (42). La plaque de montage (40) de brosse comprend au moins trois segments de montage (44) s’étendant depuis une surface extérieure (42b) du corps principal (42) radialement vers l’extérieur, lesdits segments de montage (44) étant circonférentiellement répartis autour du corps principal (42) de la plaque de montage (40), chacun des segments (44) entourant localement le support (32) de la brosse (30) de mise à la terre en restant radialement à distance dudit support (32).Grounding brush assembly (20) comprising a grounding brush (30) and a brush mounting plate (40) configured to axially and radially retain said brush (30), said brush (30) comprising a support (32) and a plurality of individual conductive fibers (31) mounted in said support (32), the mounting plate (40) comprising a radial main body (42) delimited axially by a first front face (41a) and by a second front face (41b), and a plurality of tabs (46) for axial and radial retention of said brush (30), said tabs (46) being circumferentially distributed around the main body (42) of the mounting plate (40 ) and extending axially from the second front face (41b) of the main body (42). The brush mounting plate (40) includes at least three mounting segments (44) extending from an outer surface (42b) of the main body (42) radially outward, said mounting segments (44) being circumferentially distributed around the main body (42) of the mounting plate (40), each of the segments (44) locally surrounding the support (32) of the grounding brush (30) while remaining radially at a distance from said support (32 ).
